SPRING BUTT-HINGE.

SPECIFICATION forming part of Letters Patent No. 704,487, dated. J' uly 8, 1902.

Applicationled October 9, 1901.

To @ZZ whom t may concern:

Be it known that we, THOMAS H. PENTY and WILLIAM L. BULLARD, residents of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Spring Butt-Hinges; and we hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which ro it pertains to make and use the same.

' Our invention relates to improvements in spring butt-hinges.

The object of our invention is to produce a spring butt-hinge which is exceedingly simple and durable in construction and reliable in its operation, which has its leaves normally swung together or bearing against each other, and which has the spring, axial pin, and leaves so assembled as to render the spring 2o free to be removed in the normal position of the leaves upon the withdrawal of the pin.

Vith this object in view our invention consists in certain features of construction and combinations of parts hereinafter described,

z5 and pointed out in the claims.

In the accompanying drawings, Figure I is a top plan in section of a door hinged to a jamb of a door-casing by a hinge embodying our invention with the door closed and the 3o leaves of the hinge in their closed-together or normal position. Fig. II is a plan of the same with the door and the jamb in section and with the door swung open against the action of the spring of the hinge. Fig. III is an elevation on line III III, Fig. II, and portions are broken away and in section in Fig. III to more clearly show the construction. Fig. IV is a side elevation of the hinge detached. Fig. V is a vertical section on line V V, Fig.

4o IV, looking toward the axial pin of the hinge. Fig. VI is an end view of the spring of the hinge.

Referring to the drawings, a designates the door-supporting jamb of a door-casing, and

b represents a door hinged to the said casing by means of a hinge embodying our invention.

Our improved hinge comprises two vertically-arranged leaves c and d, having vertically-arranged registering ears c, c2, d', and

5o (7.2 and a correspondingly-arranged axial pin serai No. 78,066. uit time.)

or pintle e extending through the said ears. The jamb-engageable leaf c, known as the jamb-leaf of the hinge, is provided with any suitable number of lateral holes g for the reception of screws oo, instrumental in securing the said leaf to the jamb of the door-casing.. The leaf d, which is attached to the door uponthe application of the hinge and known as the door-leaf of the hinge, is provided with any suitable number of lateral 6o holes 7L for the reception of screws y, instrumental in securing the saidfleaf to the door which is to be hung to the aforesaid jamb.

The jambleaf c of the hinge illustrated is provided at'its inner side edge with two ears 65 c and c2, arranged a suitable distance apart and in line vertically and affording a support or bearing to two ears d' and d2, respectively, formed upon and at the inner side edge of the door-leaf d. therefore, with two ears d and d2, arranged a suitable distance apart vertically and in line withrand resting upon the ears c and c2, respectively, of the jamb. The axial pin e extends vertically through the aforesaid ears fr, d, d2, and

The pin e is provided at its upper end with a head e', which overlaps and rests upon the upper end of the upper ear d of the door-leaf d. The pin e is therefore removable upwardly 8o from within the ears c2, d2, c', and d.

A torsional coiled springfis interposed between the lower or innerend of the upper ear `c' of the jamb-leaf c and the upper or inner end of the lowerl ear d2 of the door-leaf d. 85 The springf comprises a series of coils surrounding the pin c. The springfhas opposite end coils thereof terminating at one and at the same side of the spring in arms f and f2, respectively. The arms f and f2 project 9o laterally of the side of the spring. Thearms f and f2 are arranged with the leaves c and cl between them and as the spring is normally under tension act to retain the said leaves closed together, so that a door hung to a jamb 9 5 by ourimproved hinge will be normally closed and retained in its closed position by the action of the spring and when swung open places the spring under more tension. The

spring f when detached has its arms f and f2 roo The door-leaf d is provided, 7o i crossing each other in end elevation of the spring, as shown in Fig. VI, or at least converging from the end coils, from which the said arms project, so that the spring upon its application has its said. arms spread apart to accommodate the interposition of the leaves c and d between them and to place the'spring under some tension, and the arms f andfz when thus spread and applied are parallel or approximately parallel, as shown in dotted lines,.Fig. I.

The arms f and f2 of the end c'oils of the spring f engage and are preferably slid endwise into, and consequently withdrawable from, horizontally-arranged grooves, which are formed in the leaves of the hinge. As

` illustrated, the arm f2 of the lower end coil of the springf engages a groove c3, formed in and transversely of the jamb-engageable or inner side of the jamb-leaf c at a right angle to the axial line of the hinge, which groove c3 is open at the inner side edge of the said leaf to accommodate the sliding of the engaging spring-arm f2 endwise into and out of the groove. The arm f of the upper end coil of the spring f engages a groove d5, formed in and arranged transversely of the door-engageable or inner side of the door-leaf d, which groove di is open at the inner side edge of the said leaf d to accommodate the sliding of the engaging spring-arm f2 endwise into and out of the said groove d3.

In applying our approved hinge to a door and door-casing the leaves c and el are attached to the door-supporting jamb of the said casing and to the door, respectively. rlhe door is then placed in its closing position, wherein the leaf CZ will be closed against the leaf c with the grooves c3 and d3 parallel or approximately parallel. Then the springfis placed in position by interposing it lengthwise between the upper ear c of the jambleaf and the lower ear d2 of the door-leaf with the arms or members f and f2 spread apart and slid into the grooves d3 and c3, respectively, whereupon the axial pin e of the hinge is introduced by sliding it into place from above through the upper ears of the leaves and through the coils of the spring into the lower ears of the leaves. Obviously, therefore, the removal of the door from the doorcasing can be eected with facility, necessitating only first the endwise withdrawal of the axial pin e from within the spring to accom modate the withdrawal of the spring and requiring only the withdrawal of the spring after the withdrawal of the pin to detach the leaves of the hinge from each other and render the door free to be removed from the door-casing. In the normal position of the parts, as shown in Figs. IV and V, the two leaves of the hinge are swung together and the spring, which acts to hold the vleaves in the said position, is rendered free to be withdrawn from between the ears c and cl2 upon the removal of the pin e. It will also be observed that there is no load endwise upon the spring when remet the hinge is applied, because the door-.leaf d at its ears d and d2 is supported from and upon the ears c c2 of the jamb-leaf c.

1. Aspringbutt-hinge havingits leaves normally swung together and provided, at their inner side edges, with ears arranged in line longitudinally of the said edges; a torsional coiled spring interposed lengthwise between two of the said ears and having two arms projecting laterally of the same side of the spring and arranged with the leaves of the hinge between them and acting to hold the leaves swung together, and the axial pin arranged within the aforesaid ears and spring and withdrawable endwise,substantially as and for the purpose set forth.

2. A spring butt-hinge having its leaves normally swung together and provided, at their inner side edges, with ears arranged in line longitudinally of the said edges; a torsional coiled spring interposed lengthwise between two of the said ears and having two parallel orapproximately parallel arms projecting laterally of the same side of the spring and are ranged with the leaves of the hinge between them and acting to hold the leaves swung totogether, and the axial pin arranged within the aforesaid ears and spring and withdrawable en dwise, substantially as and for the purpose set forth.

3. Aspringbutt-hingehavingitsleaves normally swung together and provided, at their inner side edges, with ears arranged in line longitudinally of the said edges; a torsional coiled spring interposed lengthwise between and in line with two of the said ears and having two arms slid intothe inner side of the dif ferent leaves, respectively, and acting to hold the leaves swung together, and the endwisewithdrawable axial pin extending through the coils of the spring and engaging the aforesaid ears interiorly, and `the leaves having their inner sides grooved to accommodate the reception of the-aforesaid arms of the spring.

4. Aspringbutt-hinge havingitsleaves normally swung together and provided, at their inner side edges, with ears arranged in line longitudinally of the said edges, a torsional coiled spring interposed lengthwise between two of the said ears and normally under tension, which spring has its two end coils terminating in two arms projecting laterally of the same side of the spring and engaging the inner side of the different leaves, respectively, and converging from the said end coils when the spring is detached, and the endwise-withdrawable axial pin extending through the coils of the spring and engaging the aforesaid ears internally.
